Calculation of Number of Electrons in 100g of CO2

Step 1: Find the Molar Mass of CO2

The molar mass of CO2 (Carbon Dioxide) can be calculated by adding the molar masses of Carbon and Oxygen.

Molar mass of Carbon (C) = 12.01 g/mol

Molar mass of Oxygen (O) = 16.00 g/mol

Molar mass of CO2 = (12.01 g/mol x 1) + (16.00 g/mol x 2) = 44.01 g/mol

Step 2: Calculate the Number of Moles of CO2

The number of moles of CO2 can be calculated by dividing the given mass by the molar mass of CO2.

Number of moles of CO2 = Mass of CO2 / Molar mass of CO2

Number of moles of CO2 = 100 g / 44.01 g/mol = 2.27 moles

Step 3: Find the Number of Electrons in CO2

Carbon dioxide (CO2) consists of one carbon atom and two oxygen atoms. The atomic number of carbon is 6, and the atomic number of oxygen is 8. Therefore the number of electrons in CO2 can be calculated as follows:

Number of electrons in carbon = 6 electrons

Number of electrons in oxygen = 8 electrons x 2 atoms = 16 electrons

Total number of electrons in CO2 = 6 + 16 = 22 electrons

Step 4: Calculate the Total Number of Electrons in 100g of CO2

The total number of electrons in 100g of CO2 can be calculated by multiplying the number of electrons in CO2 with the number of moles of CO2.

Total number of electrons in 100g of CO2 = Number of electrons in CO2 x Number of moles of CO2

Total number of electrons in 100g of CO2 = 22 electrons x 2.27 moles = 49.94 electrons

Therefore, the number of electrons in 100g of CO2 is approximately 49.94 electrons.
